ii. Socio-cultural influences: Further exploration of socio-cultural factors influencing students' dietary decisions, including peer influence, cultural norms, and social dynamics, can inform culturally tailored interventions to support healthy eating behaviours.

iii. Stress-related eating behaviours: Understanding the complex relationship between stress, emotional eating, and academic performance can inform interventions targeting stress management and healthy coping mechanisms among students.

iv. Campus environment: Assessing the role of the campus environment, including food availability, accessibility, affordability, and marketing strategies, in shaping students' nutritional choices can guide policy development and environmental interventions to support healthy eating on campus.

v. Technology-based interventions: Exploring the use of technology, such as mobile applications and online platforms, for delivering nutrition education and promoting healthy eating behaviours among students can capitalize on digital advancements to reach a wider audience.

In summary, by addressing these research gaps and implementing evidence-based interventions, universities can play a pivotal role in fostering nutritional health and academic success among their student populations. Through interdisciplinary collaboration and a holistic approach to supporting students' well-being, universities can create environments that empower students to thrive academically and lead healthier lives.
